" I claim:

fIhe combination with a concave reflector, a

light bulb supported by said reflector at its center, of a device for controlling the direction-ofthe rays from the bulb, said device comprising a portion of the concave reflector, the planes being at angles with each other, the first, plane extending downwardly and-forwardly below the front o a p r wt lb .t s ond p ane extending downwardly andbackwardly below the lower front half of the bulb, and the third plane extending backwardly, andupwardly below the lower back halfof the bulb, the sides of the bulb being left uncovered'gandmeans for resil-f iently attaching said controlling device to; the b'u1b,.said last mentioned means comprising U- shaped: loops having legs secured to opposite plane portions of the controllingdevice, whereby the said loops may grip the bulbalon'g opposite sides of the longitudinal axis thereof.
